Study Details

Brief summary:

This phase I trial tests the safety, side effects and best dose of ruxolitinib in combination with cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) chemotherapy and how well the combination works in treating patients with untreated nodal T-follicular helper (TFH) cell lymphoma. Ruxolitinib phosphate blocks a protein called janus kinase, which may help keep abnormal blood cells or cancer cells from growing. It may also lower the body's immune response. Ruxolitinib phosphate is a type of tyrosine kinase inhibitor. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It may also lower the body's immune response. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Doxorubicin is a type of anthracycline antitumor antibiotic. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Giving ruxolitinib in combination with CHOP chemotherapy may be safe, tolerable, and/or effective in treating patients with untreated nodal TFH cell lymphoma.

Follicular T-cell lymphoma (FTCL)(WHO4R)/TFH lymphoma, follicular type (ICC)/ nodal TFH cell lymphoma, follicular-type (WHO5)
Must be planned to receive full course (6 cycles) chemoimmunotherapy as per clinical standard of care for untreated nodal TFH cell lymphoma

Measured or calculated creatinine clearance ≥ 60 mL/min (glomerular filtration rate \[GFR\] can also be used in place of creatinine clearance \[CrCl\])

Creatinine clearance should be calculated per institutional standard
Serum total bilirubin ≤ 2.0 x upper limit of normal (ULN)

(Patients with documented liver or pancreatic involvement with lymphoma may be enrolled if total bilirubin ≤ 3.0 x ULN. Patients with documented Gilbert disease may be enrolled if total bilirubin ≤ 5.0 x ULN) OR direct bilirubin ≤ ULN for patients with total bilirubin levels > 1.5 ULN
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase \[SGPT\]) ≤ 3.0 x ULN OR ≤ 5 x ULN for patients with liver involvement
International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 x ULN

Activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN

Note: unless patient is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants, or patient is shown to have an antiphospholipid antibody on workup
For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of ≤ 1% per year during the treatment period and for at least 4 months after the last dose of study treatment. Women must refrain from donating eggs during this same period. A woman is considered to be of childbearing potential if she is post-menarchal, has not reached a postmenopausal state (≤ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements. Examples of contraceptive methods with a failure rate of ≤ 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not acceptable methods of contraception
For women of childbearing potential, a negative serum pregnancy test result during screening period. Women who are considered not to be of childbearing potential are not required to have a pregnancy test
For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm, as defined below: With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 4 months after the last treatment. Men must refrain from donating sperm during this same period. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not acceptable methods of preventing drug exposure. Male patients considering preservation of fertility should bank sperm before study treatment

Prior systemic treatment or radiation for T-cell lymphoma except for patients who require lymphoma symptom control during screening may receive steroids in the following manner:

Up to 30 mg/day of prednisone or equivalent may be used for lymphoma symptom control during screening, including prior to finalization of staging (not included as part of pre-phase treatment). If glucocorticoid treatment is urgently required at higher doses for lymphoma symptom control prior to the start of study treatment, tumor assessments must be completed prior to initiation of > 30-100 mg/day of prednisone or equivalent. Prednisone > 30-100 mg/day or equivalent may be given for a maximum of 7 days as a pre-phase treatment. If patients exceed the allowed dosing of corticosteroids, patients may still be eligible for the study provided that baseline imaging is performed (or repeated) after completion of the course of higher dose of steroids. Allowed corticosteroid dosing resets from the point of imaging forward and patients who do not exceed the allowed corticosteroid dosing from the point of imaging until initiation of study treatment may enroll

Use of medications or consumption of foods that are strong inducers or inhibitors of cytochrome P450 (CYP)3A must be discontinued at least 2 weeks prior to study intervention. Patients who (after enrollment) require use of a strong CYP3A4 inhibitor to treat a fungal/mold infection will require dose reductions
